HOOK.

Patented Feb. 5, 19077.

Application filed January 2, 1902. Serial No. 88,115.

form a hook and having a raised collar provided with an abutting shoulder to receive a washer and hold it from'longitudinal movement on the hook. -Fig. 2 represents the washer detached from the hook. Fig. 3 represents a hook similar to that shown in Fig. 1, but with the washer applied thereto. Fig;

4 represents the hook in side view after the retainin wings or spurs have been formed, the washer being shown in sectional view.

Fig. 5 is a similar view to that thown in Fig.

8, but with the hook turned one-quarter turn. Fig. 6 is a transverse sectional view through the body of the hook on the plane of the projecting wings E E, and Fig. -7.repre sents the tompletedhook with the end or tip designed to enter the woodwork pointed and provided-with a screw-thread.

Similar reference letters and figures referto similar parts in the difl'erent views.

The'obj eat of my present invention is to produce a screw ordrive hook rovided with a screw-threaded tip by whic it is attached to the woodwork and having a cup-shaped washer adapted to be drawn against the woodwork, by the insertion of the hook therein, said washer being held from longitudinal mov'ement on the hook by the abutting shoulderof araised collar integral with the body of the hook and adapted to resist the pressure of the washer against the woodwork and having jecting wings or spurs integral with the body of the hook and bearing a ainst the opposite side of the cup-shaped washer to revent its accidental removal from the 1100 as hereinafter pointed out in the annexedv claims. 7

Screw ordrive hooks are now in common use provided with a raised collar 'i'nte ral with the body of the hook and provided with an abuttin shoulderand having a washer loosely app ied to the body of the-hook, as shown in Fig. 3 of the drawings. In hooks of this construction, however, with-the washpro- ers looselyapplied to the body of the hook the hook and washer are liable to be separated and the washer lost. In my improved hook I obviate this difficulty by forming, preferably on diametrically opposite sides, projecting spurs or wings integral with the ody of the hook and oearin against the front or concave side of the was er, by which the washer is held in contact with the raised collar and firmly held upon the body of the hook, and I accom lish this result by the process hereinafter escribed.

Referring to the drawings, Fig. 1 'repre--- sents what I term a hook-blank, consisting of a plain piece of wire A, bent at one end to form a suitably-shaped hook and provided a short distance from 1ts opposite end with a raised collar A", having on one side an abutting shoulder A at right angles with the axis of the hook. A on -shaped washer B, Fig.

2, is then stam ed om sheet metal, having a hole B to ena 'le thesvasher to be applied to I the hook and bear against the shoulder A as represented in F i 3. I-next compress the body of the hookin front of or on the concave side of the washer B between a pair. of reciprocating dies, said dies being so shaped and so arranged that the metal of the hook immediately in front of or'on the concave side of the washer B is pressed laterally out-- ward to form on diametrically opposite sides of the hook-projecting spurs or wings E E, which bear against the front or concave-side of the washer B, thereby preventing the removal of the washer fromthe bodyof the hook, as shown in Figs. 8, 9, and 10.-

I do notvconfine myself to wings or spurs of the shape shown for the purpose of retaining the washer against the collar A, as the number and shape of the wings can obviously be varied and produce the same result. The

purpose of my invention is secured by the" employment of a radially-projecting mass of metal integral-with the body of the hook by which the washer is held from sliding off .the end or tip D of the hook, with said projecting mass of metal forming Wings or spurs inclosed within the concave side of the washer, 4

whereby the edge of the washer is brought into contact with the'wo'odwork and the hook ermitted to turn Within'the washer as the iiook is screwed into the woodwork. While the difliculty of the facile detachability and consequent liability to loss of the washer by firmly fastening said washer to the hook, this would give rise to the disadvantage that the washer would then turn with the hook and mark and otherwise mar the surface of the woodworkinto which the hook was inserted. In my hook, however, the washer, while held from longitudinal movement toward either end of the hook, is nevertheless indef' endent of it and allows the body of the hoo to rotate freely. without revolving the washer.

What I claim as my invention; and desire to secure by Letters Patent, is-I- 1. As an article of manufacture, a' hook provided with a shoulder, a cup-shaped washer held on said hook with its convex side bearing against said shoulder, and a spur radially projecting from the side of said hook and inclosed within the concave side of said washer.

2. As an article of manufacture, a hook consisting of a single iece of wire provided with a screw-threade tip at one end and a hooked section at the opposite end, a raised shoulder between the tip and the hooked section, a concaved washer held on the wire with its convex side against said shoulder, and a pair of radiallyrojecting spurs integral with the wire and inc osed within the concave side of said washer.
